Glycolipid synthesis in recombinant E. coli. A, TLC of lipid extracts from E. coli cells expressing mg517, mg060, and mg025 genes, respectively. BL21 are control cells transformed with the pET38b(+) with no insert. B, TLC-autoradiography of in vivo glycolipids from M. genitalium grown in [14C]glucose medium (lane 1 labeled Myc) and in vitro products from GT assays with spheroblasts of E. coli cell expressing mg517, mg060, and mg025 genes incubated with UDP-[14C6]Glc, DOG, and SDS. GL1, GL2, and GL3, glycolipids; TG, triglycerides.
